[Haskell-cafe] Documentation on the internals of Hugs

[KwangYul Seo]

Hello,

I want to study the internals lof Hugs, but the only document I got is:

The implementation of the Gofer functional programming system
http://web.cecs.pdx.edu/~mpj/pubs/goferimp.html

I see Gofer is the predecessor of Hugs, but I am not sure how much the
code base has been changed since then.
Are there more recent documents on the internals of Hugs?

Regards,
Kwang Yul Seo
